throttle switch.
I'm finding *many* vanagon throttle switches not making contact at idle.
I'm finding the later type switches ( where it's one switch mounted under
the throttle body , which is late 85 1.9's and all 2.1's ) ........that they
are hard to get to an adjustment, or to 'reach' a spot with proper switch
function - like I'm at the limit of the adjustment range on one end.

I'm also finding them corroded, stripped, and impossible to adjust.
That the ECU knows the engine is at idle, is *very* important.
Suggest you check that carefully.

Having a similar problem w/ my 86 Syncro, even after new Temp 2 sensor
and O2 Sensor.  Pugs/wire/cap/rotor also new.  Going to clean grounds
next, then dive into the AFM.  But I'm interested in any continued
advice to feed the back of my little brain.

Thanks,
